Cool ! Would be nice if somebody will produce such a device from the customer's cartridge.
My soldering skills are not good enough to build it.

I'm not either good at soldering Tongue. Would it be possible for someone to get the responsability to build this hardware?. If I'm not wrong, it's the first "alien" hardware to be supported under SymbOS providing its own driver Smile
